I'm the evil mastermind
Dr. Ulof explains the machine in the lab with technobbabbly Mr Scott of
Star Trek couldn't decypher. Ulof zaps a guinea pig which turns invisible and is later
returned to visiblity.

Of course, science is at work...
Later Joey knocks out the the guard, and sneaks back into the lab.

So, that makes me the hero....
Ulof reveals that Krenner is holding his daughter prisoner to force him tow work for him.

C'mon Doc, you gotta know how to fix a flux capacitor...
During World War 2, Ulof was experimenting when Krenner captured him.
Joey tries convincing Laura to join him.
The next day, in the lab, Joey is readied for turning invisible ( in a non Scott Baio-Zapped way...) Once invisible, Krenner forgot that he couldn't hold Faust
very easily. Choking Krenner, Faust gets a pay raise.

Why one shouldn't anger the invisble...
At a nuclear plant,, Faust walks past the guards and cracks the safe containing the radioactive materials.
Back at the lab, Ulof finds the guinea pig dead. Invisibility slowly kills those are invisible. Krenner wants Ulof to use the new X-13 material the next time on Faust
even if it is more dangerous.
Faust is turned invisible again to hit the nuclear plant again. On the way, he decides to rob a bank instead. Walking out of the bank carrying a bag on money, Joey
starts fading in and out of visibility.

'Don't lose your head' you think that's funny?
Teh security group from the nuclear plant knows about Joey being invisible.
Back at the ranch, Krenner hears of Joey's bank robbery.
Joey leaves Laura away and heads back to Krenner's ranch.
Krenner tries to convince Ulof to redo the formula and will free Maria, too. Faust knocks Krenner outUlof and Maria vow to help correct Joey from fading in and out
of visibility. Ulof reveals Krenner's secret plan to create an army of invisible soldiers. Faust heads back to the ranch when he learns he only has a few days or weeks left
at most.
Ulof and Maria get away. Laura rushes back to the ranch but is shot by Krenner. The fight is down to Krenner and partially visible Faust. Krenner tries the invisibility
ray to zap Faust again. However, the X-13 compund reacts badly with the ray, and Big Badda Boom of an atomic bomb cloud ensues.

How science fiction must end in the 1950s....
Security guys examine the wreckage of the ranch from a distance. Ulof tells them how Krenner wanted to create an army of invisible soldiers.
